This Catharus occupies the higher portions of the range of C. mexicanus 

 fumosus, mingling with that species to some extent, but while mexicanus 

 is most abundant at about 2,000 feet, this bird is commonest at about4,ooo 

 feet. Its range is the same as that of the following species, except that 

 it is also found in small numbers in the Dota Mountains, and extends 

 down the Caribbean slope the whole length of the country. Like mexi- 

 canus, it is found only in the heavy forest. 



I secured a nest of this species at Juan Vifias, May 20, 1907, containing 

 two fresh eggs. The female was incubating, and secured when flushed. 

 The nest is not so pretty a structure as that of mexicanus, being constructed 

 of leaves, moss, and weed-stems, and lined with fine weed-fibres and grass. 

 It was placed in a low bush in the heavy forest. The eggs are pale blue, 

 thickly speckled and dotted and blotched over the entire surface with 

 light chestnut-rufous. Measurements: 25X18 mm.
